ANCHOR-PLATE FOR FENCEPOS'IS.

Specification of Letters Patent. 7 Patented N 30 1920 Application filed May 5, 1919. Serial No. 294,887.

1 '0 all whom it may concern:

Be it known that I, BROOKE ANDERSON a citizen of the United States, residing at Highland Park, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Anchor-Plate for Fenceposts, of which the following is a specification.

This invention has for its object the rovision of a device of the class named w ich shall be of improved construction and operation.

The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawing and described in the following specification, and it is more particularly pointed out in the appended claims. I

In the drawing Figure 1 is a side elevation of a fence post to which one embodiment of the present invention is applied; v

Fig. 2 is a view looking from the left in Fig. 1;

Fig. 3 is a section on line 33 of Fig. 1; and

Fig. 4 shows a modification of the anchor plate. I v Although the present invention is applicable to various forms of fence posts, it is shown in the drawing as attached to a steel angle bar post, such as are placed in the ground by driving. The post is provided with two flanges 10 and 11 which make up the angle bar, one of the flanges being pierced by a number of holes 12 by which the wires are secured to the post. The flange 10 to which the wires are preferably fastened extends in the direction of the plane of the fence when the post is in position in the ground. The bottom end of the post is pointed, as shown at 13, to facilitate driving. Secured to the flange 10 by rivets 14 is an anchor plate 15, preferabl made of sheet metal, and located lntermedlate the lower end of the post and the portion of' the post which is positioned at the ground line, when 'the post is set. It will be seen that the late 15 is attached to the flange 10 so that it will extend in the direction of the plane of the fence. The late is substantially trian lar in shape wlth one pointed end, exten ing downwardly so that it will enter readily into the ground as the The position of the plate relativeto the direction of the fencing enables it to resist lateral movement occaslonedby pressure against the fence; The post ord1nar1ly is not subjected to pressure longitudinally of the fence for the reason that the wires are free to slide in their fas-' tenlngs on the post, and any pressure brought upon the fence is transverse to the plane thereof. The plate is preferably positioned below the ground line so that the earth will form a cushion above the plate. In this way the resiliency of the post permits slight yielding under lateral pressure on the fence, and slnce the post is not held fixed. at the ground line there is not so much danger of producing a permanent bend in the post at this point. It will be seen from the drawing that the plate 15 is provided with ribs 16 struck up from the metal of the late and arranged in the form of awide the arms of which extend downwardly and inwardly from the extreme lateral portions of the plate. The rib 16 has several functions, probably the most important of which is to strengthen the plate against transverse bending. If a flat plate were used it will be apparent that the projecting portions would easily bend laterally against the edges of the flange 10 to which the late is secured. This bendin might take p ace in shipping the posts, an it is also liable to occur when a heavy lateral strain is brought upon the fence after the post is in place, thus permitting the post to be moved transversely in the earth. Where strengthening ribs 16 are used such lateral bending of theprojecting portions of the 0st is prevented, and the plate may be ma e of lighter weight material than would be otherwise necessary. The ribs 16 also tend to resist upward movement of the post after the earth has become packed against the plate. The fact that the rib is struck outwardly from the plate produces not only a pro ection on one side of the plate, but a depression on the opposite side extreme lateral portions of the plate without this arrangement makes it more convenient to secure the upper rivet 14 in place.

I claim 1. In combination, a post and an anchor plate secured thereto, said plate having a strengthening rib struck up thereon and the longitudinal axis thereof extending transversely of said post and in a direction inclined to the horizontal.

'2. In combination, a fence post and an anchoring device secured thereto,said anchoring device comprising a flat plate at, tached to said post and provided with a substantially V-shaped strengthening rib formed thereon and having the arms thereof extending transversely of said post.

3. In combination, a fence post having a flange thereon againstwhich fencing is secured, and ananchor plate secured to said flange and arranged to extend in the direction of the plane thereof, said plate having strengthening ribs formed thereon and extending transversely of said post and across the edge of said flange so as to resist bending of said plate in a direction transverse to the plane thereof.

4. In combination, a fence post and an anchor plate secured thereto, said plate having a strengthening rib formed thereon by a corrugation in said plate so that said rib extends outwardly from the plane of said plate on one side thereof producing a groove or depression von the side of said plate opposite said rib, said rib being arranged to extend across the line of contact.between said post and plate.

5. In combination, a post and an anchor plate secured thereto, said plate having a strengthening rib formed thereon and extending transversely of said post, said rib comprising a corrugation formed in the material of said plate so that, said rib extends outwardly from the plane of said plate on one side leaving a depression on the opposite side of said plate, said plate being secured to said post with the side thereof having the depression therein lying against said post.

6. In combination, a fence post andan longitudinal axes extending inwardly and downwardly from opposite' sides of said plate, and means for securing said plate to said post at a point within the angle formed by said strengthening ribs.

In combination, an angle bar fence post having one flange thereof provided with openings for securing fencing thereto and having one end thereof sharpened to permit said post-to be driven into the earth,

an anchor plate secured to said post between the ground line and the lower end thereof and lying against the face of the -flange' provided with said securing openings, a strengthening rib formed on said plate and comprising corrugations projecting laterally from the face of said plate so as to leave depressions on the sideof said plate adjacent said post, said corrugations being arranged to extend inwardly and downwardly from opposite portions of said plate and across the edges of said flange to which said plate is secured, and an attaching member positioned within the angle formed by said corrugations for securing said plate to said post.

9. In combination, a post and (a triangularly shaped anchor plate secured thereto with one apex of said triangle lowermost, said plate having a V-shaped strengthening rib formed thereon with the arms of said V extending inwardlyand downwardlyfrom the upper corners of said triangular plate.

In testimony whereof I have signed my name to this specification on this 2nd day of May, A. D. 1919.
